ylhis invention has reference to threshing machines, the primary object ot the invention being to provide pneumatic means` for discharging the grain into the granary or other place of deposit for the threshed grain.

An important object of the invention to provide means wherelrv the passageway or spout through which the grain is delivered to the discharge pine, will be closed at credetermined intervals, or when a certain Quantity ot `Qgrain has passed trom the spout, so that the air Yfrom the blower will not cause a back pressure in the spout to ca se the `grain to clog.

A still further ohject ot the invention is to provide an attaclnnent of this character which may be readily and easily installed on threshing machines new in use elin'iinating the necessity of matting a'ltf'frations in the threshing machine construction to in;tall the device.

With the foregoing; and other objects in view` which will appear as the description proceeds. the invention resi-fles in the conibination and arrangement of parts and in the details ot construction hereinafter described and claimed. it beine understood that n V`VV`es in the precise embodiment of the invention herein disclosed, may be made within the scope oi what is claimed, without rleit-arting trom the spirit ot the invention.

Referring: to the drawinggjs:

Figure 1 is a trapgmental Ulan vieiv et a threshing machine showing an attachment constructed in accordance with the invention, as positioned thereon.

Figure Q is fraginental sectional view through the dcliverv snout and blower snout.

Figure 3 is a sectional view te Ten richt angles to Figure 9.

Figure is a tragmental sectional view tlirough the deliveryv snout and blower the automatic closure being shown in position.

Figure 5 is a sectional view taken on line 5-5 of Figure 1.

Referring to the drawings, the reterence dliaracter 5 designates the body portion of a threshing machine, to which the attachment 1929. Serial No. 369,718.

forming the subject matter ot this invention, is secured.

The attachment comprises a blower housingea 6 secured to the threshing machine frame, by means ot the bracket 7 which is bolted to the threshing machine frame by means of the bolts 8. l'ilanaes 9 extend laterally from the bracket and are provided with openings to receive the bolts 10 which also pass through evenings in the blower housing;` 6. The blower housing' G includes a pipe 11, to which the tapered pine section 12 is secured, which pine section 12 Jforms a part ot the blower pipe or discharge pipe, the extension 13, which also forms a part ot the blower pipe being of any desired length.

rllhe reference character 14 designates the delivery spout which communicates with the i:liier-:lrmV machine to receive the grain after it has passed tl'irougxh the various beaters and screens ot the threshingy machine. A worm indicated at 15 operates in the delivery spout and acts to feed the `grain laterally into the pine section 12. Secured within the pine section 1Q, a spring arm 16 that carries 75 a dish like closure 17 at its free end.` the disk like closure beinf ot' a diameter to fit over the discharge end ot the delivery spout 14. so that under normal conditions` that is when no lPressure exerted against the inner surface of the closure 17, the action ot the snringr sinkiportingy arm 1G will be to close the opening: however the closure 17 will move to its onen position, or to a position as shown by Figure l of the drawings, under the nre, `re oi the grain beine; forced through the delivery spout 14, by the worm conveyer.

lt ot course obvious that as the (grain is fed into the blower nine. the blast of air pass- 90 in gr through the blower pine will nick up the grain and carry the grain through the blower pine where it may be discharged into the granary or place ot storage.

I claim:

ln a device of the character described, a main pipe section, a tapered pipe section communicatin,aa with the main pipe section, a delivery snout disposed laterally ot the tapered pipe section and communicating therewith, a spring arm secured Within the tapered pipe section, a disk-like closure at the free end of the arm and adapted to normally close one end of the delivery spout, a spiral eonveyer Within the delivery spout for forcing grain against the disk-like closure to force the closure to its open position, and means for directing a blast of air through the main pipe and tapered pipe section, to piek up grain and carry grain through the tapered pipe section. e

In testimony that I claim the foregoing as my own, I have hereto atlixed my signature.

ANNA KALTENBRUNN.
